\item{\code{signature(x = "DotStack", i = "ANY", j = "missing")}}{
\code{i} indexes the \code{DotStack} object's x coordinates like a regular vector; however, a matrix is returned including both the requested x coordinates and their corresponding y values.
}

\item{\code{signature(x = "VAObject")}}{Works by creating a two column matrix of the left and right eye logMAR values and passing to the default extraction method for matrices.}
